Yes - due to popular demand it's back again for 2022. The route will be slightly changed this year - but it remains a spectacular run - around and down from Gilwern Hill, a traverse of “The Tumble” and an excursion through the lava-like landscape of the canyons of Pwll Du... and who could forget the finish up and down the infamous volcano?

This gives an approximate distance of 5 / 6 miles.

It really is the most interesting off-road race, with some spectacular scenery set amongst a backdrop of remote moorland-like areas and old quarry workings. A route for connoisseurs! A route for those who like a challenge! 

Covid: We will have obviously make sure the event conforms to guidelines/regulations at the time and always give particpants the opportunity to distance themselves during the start process.
